SPECIFICATION forming part of Letters Patent No. 690,912, dated January7, 1902. Application filed December ,1899. Renewed July 28,1901. SerialNo. 69.825. (No'modal.)

A acitizen of the United States, and a resident of Espy, Pennsylvania,have invented certain Improvements in Woven Pile Fabrics, of which thefollowing is a specification.

My inveution'relates to that class of pile fabrics having a pile surfacecomposed partly of cut or tufted pile and partly of uncut or loopedpile, the object of my invention being to produce a fabric of thischaracter in which the cut-pile gures shall have a we1l-dened outlineand in which the cut pile shall be of the same height as the uncut pile.

In the accompanying drawings, Figure lis a face view of a piece offabric embodying my invention. Fig. 2 is an exaggerated sectional viewof a piece of the fabric, the se tion being taken transversely'or in thedirection of the weft-that is to sayfon the line a a,.l1`ig. 1. Fig. 3is a like exaggerated sectional view of a piece of the fabric, the sec-ltion being taken longitudinally or in the direction of the warp-that isto say, on the line b b," Fig. 1; and Figs. 4, 5, and (i are viewsillustrating a method and means which may be employed forproducing myimproved fabric.

Heretofore'in the manufacture of pile fab ries having a pile-surfacepartly out and partly uncut it has been the practice to' producesuccessive rows of cut and uncut. pile. Thus one row would have uncutloops disposed transversely in those portions of the fabric where theuncut loopswere to appear. and the next row would have cut loopsdisposed transversely in those portions of vthe fabric where such cutloops were required, the cutting of said loops being edected either bythe withdrawal of the wire or by weaving said loops higher than theothers and afterward shearing olf the tops of the same. Two rows ofloops-that is to say, a out ro'w and an uncut row-were thus required foreach transverse line of the pattern, and the weaving of thefabric wasconsequently slower and more expensive than the weaving of an ordinaryVpile fabric having all of its loops either cut or uncut. 1t has alsobeen proposed `in producing pile fabrics with cut and uncut pile to cutolf the tops of some of the loops in a row, while leaving the remainingloops uncut; but in such case the cut loops must of necessity be of lessheight 'than the uncut loops, and it has further been proposed to pressdown part of the loops of a pile fabric and out the loops left standing;but in this case there is the further objection that the borders of thecut figureordesigncannot be sharp or well defined, owing to thenecessary disturbance of the standing loops around the edge of each areaof depressed loops..

By the method of prod ucing the fa ric forming the subject of thisinventionl th cut and uncut loops are of the same height, and theboundaries, of the out and uncut fi ures are accurately controlled, sothat perfect sharpness of outline results. Y

In Figs. 1, 2, and 3 of the drawings, 1 represents rows of loops forminguncut pile, and 2 represents rows of jtufts or cut pile in linetransversely with said pileloops, both cut and uncut pile being formedfrom a single row of loops formed over the samepile-wire.

The backing of the fabric may be" woven in any ordinary or availablemanner, that shown in the drawings comprising Studer-warps 3,binding-wefts l 4, and binding-warps 5 5.

In producing my improved fabric I use a U-shaped or other equivalentpilewire open at the top and in connection therewith a knife or knives,which may be thrust down through a row of loops formed over the wire,then be drawn along said row of loops, so as to cut the same to anydesired extent, and then withdrawn, the number of knives employed or thenumber of times the cutting operation is repeated being dependent uponthe pattern to be produced.

In Figs. l, 5, and 6 I have shown one form oi' device for carrying outmy invention, 6 representing the hollow U-shaped pile-wire, 7 a knifemounted on a bar S above the pilewire, and 9 a bar for operating saidknife, so that it may be thrust down through the Warps on the wire ormay be Withdrawn therefrom. Hence when the said bar 9 is moved in thedirection of the arrow, Fig. 4, the knife will be thrust through the rowof loops, and 1ongitudinal movement of both bars S and 9 in thedirection ofthe arrow, Fig. 5, will then cause the knife to cut theloops ofpile-thread ICO throughout that portion of the length of the rowof loops corresponding to the extent of movement of the bars while theknife is thus in engagement with the-single row of loops, a. 5 reversemovement of the bar 9 causing the withdrawal of the knife when thcdesired number of loops has been cut, as shown in Fig. 6. By this meanseach of the rows of loops formed on the pile-wires can be cut at anydesired point or points in its length.

A loom constructed for weaving my improved pile fabric forms the subjectof my application Serial No. 67,525, filed July 8, 1901.

Having thus described'my invention, I` claim and desire to secure byLetters Patent-- 1. A fabric having a pile-surface with out and uncutfig'v- 'es formed by uncut pile-loops and cut pile-tufts in the sametransverse line zo or row of pile, the loops and tufts being of the sameheight, and the outline'of the Iigures sharp and well defined,substantially as specified.

2. A fabric having a pile-surface with cut and unclnt figures formed byuncut pile-loops and cut pile-tufts in each transverse line or rowvofpile, the loops and tufts being of the same height, and the outline ofthe gures shrp and well defined, substan tiallyas specifie In testimonywhereof I have signed my name to this specification in the presence oftwo subscribing witnesses.
